How to use

Step-by-Step Guide

Step 1: Install the Framework

Well, obviously you need the framework to start working with it. :) Head over to Installation to find the correct version for you.

Step 2: Create a Trigger Handler and have it extend TriggerHandlerExension

You need to create the class the TriggerFactory instantiates. The factory expects classes of Type TriggerHandlerExtension, so to get started, use the newly installed virtual class in your own Handler class. Make sure to call super() in your constructor, or else all other functionality (including actually using the Trigger Collections) will not work.

public class ExampleTriggerHandler extends TriggerHandlerExtension{
    public ExampleTriggerHandler(){
        super();
    }
}

Step 3: Create a Trigger

Should an Apex Trigger not exist yet, you should definitely create a Trigger right about now. Make sure to include all contexts (except when handling Platform Events) and call TriggerFactory.executeTriggerHandlers(SOBJECT_TYPE_OF_YOUR_TRIGGERING_OBJECT).

trigger AccountTrigger on Account(before insert, after insert, before update, after update, before delete, after delete, after undelete) {
    TriggerFactory.executeTriggerHandlers(Account.SObjectType);
}

Step 4: Create a Trigger Factory Setting

In order to make the Trigger run, you need to create a Custom Metadata Record for the Handler you are working on. For more about the Custom Metadata driven trigger execution, check out the feature page

Step 5: Add functionality

This step is different depending on the size of your org and the structure of your other Triggers, so this is left very vague on purpose. Check Structural examples to find out what approach fits your org best.

Step 6: You're done!

What happens next is up to the rest of ongoing development - Test and Release your Triggers and start your next automation!
